" Speedindicating' devices as employed with I vehic1es,==such asmotorcycles: or automobiles areencasedjin a suitable housing' whi'ch re-I quires mounting inas favorable position as is 5 possible,sconsistentwith protection and visability. With indic'ating'deviceshaving anindexing-means requiring a manu'algcontrol,

such mounting'is at. the best for the operator, and necessitatesexcessive b movement and attention. Particularly in the Y case oftraific olficers employing a precision speedometerto register thetravelling-rate of a'traflic speed violator, it is highly desirable thatthe instrument be capable ofc'ontrol with a' minimum of arm movement anddiversion of attention. 7

' "To the accomplishment of the foregoing and related ends; theinvention,then, consists of the features heremafter' fully'described,

pointed out in the claims, the

and particularly the annex'edidrawfollowing description and ing settingforth in" detail embodying the invention, such being illustrativehowever ofbut-one'of thevarious ways in which the prlnci-pleof theinvention may be employed. V

For the purposesofillustration, 7 hand 3' which indi- 5 catestherunn ng speed'at-falltimes, and a there is shown a running maximum quite I awkward certainstructure the invention, parts being;

ment; Suitable means are provided for the release of 'the maximum handfor'res'etting, the detail being immaterial to the present in-olvention." U Means are 5 also 1 provided for the controlof the engagementand disengagemente' to hand. -Wh'etherthe stophandbea running handcapable 0t being disengaged from the driving spindle as desired, oraseparate stop'hand to ride over the running hand as-speci-ficallyillustrated, -is immaterial as re.-

disengaging means of suitable construction, theycletail of whichmay ofcourse vary, an which for the present purpose may be indiigards thegeneral control features. VWith a d'vo cated' asa lifter fork arm 6raised :and low j ered by a cam 7 suitablethrowflever 8'externally= ofthe casing makes connection tothe operatingcam through a rock-shaft 9. d

Attached to lthe throw lever 8isia push-pull element 10, preferablyawire carriedithrough a suitable guide, as an armored conduit or thelike 11 to a convenient point of control-,actuation by the operator.vThis should be within convenient range of the operators hand as normallyemployed with the steering control;

Whether a steering wheel as in an automobile or ,a'steering handle as inamotorcycle, the principle is of coursei the same", andQ-thecontrol-but-ton I2 .is by p reference Tniounte d, di: rectly' upon thesteering membenthe mounting desirably beingofadjustable type so as toaccommodate 'to the particularirequirements of right handed] or lefthanded operators,

The'control-button may be on aleverl of bell crank type, the" otherarmlwhere of connected to the push-pull element 10. Inthe form shown inFig. the fcontrol button embodiesa' thumb-piece 22 on'a'lever 13whichispivoted at p on a plate secured to 1; V

the handlebar-or steering wheel, an-d-th'e other armyl li of thebell-crank'lever i s-connected t'o'the push-pull 'wirelu foperation,:'-the runninglhand '3 will at all timesindicate the actualspeed, and the maximum hand 4 as pushed along by the running hand andretained by customary means will indicate the maximum attained. With thestop hand 5 in engagement over the running hand 3, such two hands movetogether and correspondingly show; the runposition of such stop handwill of course be maintained until it be. released to again ens gage wth the drlvmg mechanism; and when the purpose& for which the recordregistry was employed arecompleted, the reverse movement of thecontrolebutton 12 by the operatorthrows the lever 8 to engage the stop;

hand; 5 with the running hand, whereupon it again travels inconsonancextherewith.

As, will be seen,.the mobile or flexible character of theconnectinglneans between theoper-ators controhbutton and the indicatingin-v v strument allows of theutilization of most convenient locationsforeach particular part; and with the control-button directly on. thesteering means, the operator is enabled to engage and disengagetheindexingelementwith.

its drive at will, and without necessitating removal of, the hand. fromthe steering control or requiring diversion of: attention. For trafiicusage in particular, a degree of con-. venience isthus obtained making.possible a maximum of accuracyin traific checking and withtheutmost.convenience to the operator,

Other modes of applying the principle of the invention may be employed,change being,

made as regards the details disclosed, provided the means stated in anyof the follo.w-. ing' claims, or the equivalent ofsuch, be em ployed. a1
